Abstract

A method of producing shells on a rotary piercer includes rotary piercing by drive rollers on a conical mandrel of a continuous blank in a shell, continuous rolling of its front end in a gauge, calibration of the shell portion, further opening of idle rollers. The idle rollers are approached for the gauge opening that equals the outer diameter of shell, and are opened at the time of release of the conical mandrel from the metal. Upon termination of the piercing process the idle rollers are approached for the opening of gauge, which is equal to the diameter of the cylindrical mandrel.
